SPECIFICATION forming part of Letters Patent N o. 694,218, dated February 25, 1902. Application filed May 9, 1901. Serial No. 59.412. (No model.)

To @Zt whom it may con/cern:

Be itknown thatI, JOHN SVAN LEER,a citizen of the United States, and a resident of St. Louis, in the State of Missouri, have invented a new and Improved Trolley, of which the following is a full, clear, and exact description.

This invention relates particularly to attachments for electric-railway trolleys to prevent the trolley from leaving the wire, and the object is to provide a device for this purpose that shall be simple in construction and thatmay be readily attached to trolleys ordinarily in use.

I will describe a trolley embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings,forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure l'is a side view of a trolley and a guard attachment embodying my invention, and Fig. 2 is a sectional elevation thereof.

Referring to the drawings, l designates the trolley, mounted to rotate on the pin or spin dlef 2, supported in the harp 3. Arranged on opposite sides of the trolley are guard-plates 4 and 5. These guard-plates have a general elliptical form and their upper portions extend above the plane ofthe trolley, and I have here shown the upper portions or ends as curved outward to facilitate the finding of a wire and replacing the trolley thereon should the trolley from any canse leave the wire, although as a general thing these upwardlyeX- tended ends of the guards will prevent lateral displacement of the trolley. The guards are here shown as mounted to rock on the spindle or pin 2; but they may be made to rock on the hub of the trolley when said hub is eX- tended beyond the side planes of the trolley.

The lower ends of the guard-plates are connected together and weighted, as at 6. This Weight will cause the guards to maintain a position at right angles to the trolley-wire at all times, no matter at what angle the pole carried by the harp may be. By giving the guards a general elliptical shape, as shown, should they engage with a cross-wire they will be swung downward by said engagement, so as to clear and pass the same.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- A trolley, a harp in which the trolley is mounted, and guard-plates mounted between the opposite sides of the trolley and at the inner side of the harp u1embers,the said plates being connected together and weighted below the trolley, the upper portion of the plates being extended above the trolley and termi nating in a substantially pointed end, the edges at the opposite sides ot the substantially pointed end being curved downward and outward equally to the point of junction with the trolley, substantially as specified.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOHN S. VAN LEER.
